I think this would be a nightmare for code maintainance and simple
syntax. How often do you use a simple variable name like "i" for an
index? would you really want to use i in one scope, and then inner_i in
the next, and then inner_inner_i?

And as soon as you re-arranged your code a little, you would have to
re-name a bunch of stuff. I like the current scheme just fine.
